+Release Date : Thu Nov 16 15:32:35 EST 2006 -
+ Sumant Patro <sumant.patro@lsi.com>
+Current Version : 2.20.5.1 (scsi module), 2.20.2.6 (cmm module)
+Older Version : 2.20.4.9 (scsi module), 2.20.2.6 (cmm module)
+
+1. Changes in Initialization to fix kdump failure.
+ Send SYNC command on loading.
+ This command clears the pending commands in the adapter
+ and re-initialize its internal RAID structure.
+ Without this change, megaraid driver either panics or fails to
+ initialize the adapter during kdump's second kernel boot
+ if there are pending commands or interrupts from other devices
+ sharing the same IRQ.
+2. Authors email-id domain name changed from lsil.com to lsi.com.
+ Also modified the MODULE_AUTHOR to megaraidlinux@lsi.com
